All educated (and not) peoples answer me!
It's about those Ultrasonic sensors.
Why are they called that. The stuff professionally called ultrasonic doesnt normally pass through air does it? I mean when examining metal parts for aircraft and stuff, and when examining body parts, they have to use gels and stuff for that purpose. I know for other purposes as well, but YOU DONT want air in the way...
So is it just a friendly way of saying higher pitched sound or something, like bat's radar and stuff?
